Share a single PVC between multiple prometheus pods

Hi,

How do you use a single PVC across multiple Prometheus replicas.

I am using a manually created PV, I have configured the jsonnet to use the PV, using the selector. This works if there is 1 replica. If there are multiple replicas, it is expected that there is an equal number of PVs. Since the Prometheus operator generate the PVC and each PVC has a unique name.

Is there a way to configure the jsonnet so that a single PVC can be used by multiple replicas, i.e how to configure the jsonnet such that the operator generates only one PVC that will be share by all the replicas.

If I'm not mistaken for that feature you would need ReadWriteMany for the PVC and that's something that the operator won't support.
